## Role Based Access Control Error

Role based access control error refers to flaws in the implementation of systems that assign different permissions to different roles within a protocol. If the mapping between roles and functions is misconfigured, a user with a low-privilege role might inadvertently gain access to high-privilege functions.

This is particularly dangerous in complex systems where many roles exist, such as operators, owners, and minters. Ensuring that roles are correctly defined and assigned is critical to preventing privilege escalation.

Errors here often arise from overly complex role management structures.
